BACKGROUND

The present invention relates generally to thermal tabletop andindustrial printers with radio frequency identification (RFID)read/write capabilities. More particularly, the present disclosurerelates to a high speed tabletop and industrial printer with integratedhigh speed RFID encoding and verification at the same time. The printeralso discloses optimization of the communication sequence and successivememory writes in an RFID interrogator.

Radio frequency identification (RFID) tags are electronic devices thatmay be affixed to items whose presence is to be detected and/ormonitored. The presence of an RFID tag, and therefore the presence ofthe item to which the RFID tag is affixed, may be checked and monitoredby devices known as “readers” or “reader panels.” Readers typicallytransmit radio frequency signals to which the RFID tags respond. EachRFID tag can store a unique identification number. The RFID tags respondto reader-transmitted signals by providing their identification numberand additional information stored on the RFID tag based on a readercommand to enable the reader to determine an identification andcharacteristics of an item.

Current RFID tags and labels are produced through the construction of aninlay which includes a chip connected to an antenna applied to asubstrate. The inlay is then inserted into a single tag or label. Theselabels or tags are then printed by either conventional printingprocesses, such as flexographic processes, and then variable informationmay be printed either with the static information or derived informationfrom one or more components of the chip. The chips are then encoded in aprinter which has a read/encoding device or separately by areader/encoding device. This method is slow and costly due to multiplesteps that are involved in the manufacture of the product. In addition,such a method can only be accomplished typically one tag or label at atime per lane of manufacturing capability. This can result in highercost, limited output, and limited product variation in terms of size,color, and complexity. Further, current RFID interrogators limit thememory space to be written to a specific memory block and createunnecessary overhead between the printer and the writer.

Thus, there exists a need for an RFID printer that is capable of bothprinting on record members, such as labels, tags, etc., and capable ofencoding, or writing to and/or reading from an RFID transpondercontained on the record member, as well as verifying the data encoded tothe RFID tags. Further, there exists a need for a printer that printsand encodes an RFID label without stopping the web to encode the tag andreduces the overall encode time.

The present invention discloses a high speed tabletop and industrialprinter with integrated high speed RFID encoding and verification at thesame time. The industrial printer comprises two RFID reader/writers thatare individually controlled, such that the industrial printer can encodeand verify at the same time. Specifically, one of the RFIDreader/writers encodes RFID tags while the web is moving; and the secondRFID reader/writer verifies the data encoded to the RFID tags. Theprinter also provides for successive writes to various memory blocks andoptimizes the communication sequence between the interrogator and thetag. This optimization of the communication sequence in part enables thehigher throughput of the disclosed printer.

DETAILED DESCRIPTION

The innovation is now described with reference to the drawings, whereinlike reference numerals are used to refer to like elements throughout.In the following description, for purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding thereof. It may be evident, however, that the innovationcan be practiced without these specific details. In other instances,well-known structures and devices are shown in block diagram form inorder to facilitate a description thereof.

The present invention discloses a high speed tabletop and industrialprinter with integrated high speed RFID encoding and verification at thesame time. The industrial printer is capable of both printing on recordmembers, such as labels, tags, etc., and capable of encoding from anRFID transponder contained on the record member, as well as verifyingthe data encoded to the RFID tags without stopping the web. Theindustrial printer comprises two RFID reader/writers that areindividually controlled, such that the industrial printer can encode andverify at the same time. Specifically, one of the RFID reader/writersencodes RFID tags while the web is moving; and the second RFIDreader/writer verifies the data encoded to the RFID tags. The printeralso provides for successive writes to various memory blocks andoptimizes the communication sequence between the interrogator and thetag. Specifically, a configurable high level command stack is createdwhere RFID write commands are translated to EPC Gen 2 tag devicecommands, which can be sent in a single communication cycle.

Referring initially to the drawings, FIG. 1 illustrates a thermaltabletop and/or industrial printer device 100 with integrated high speedRFID encoding and verification. The thermal tabletop and/or industrialprinter 100, comprises a reader and/or encoding device, as well as averification device. The reader and/or encoding device can read andprogram an RFID device, such as a RFID chip, that is contained in aninlay which may or may not be incorporated into a label, tag, or anyother desired product, and which can also print onto the product withoutdamaging or otherwise undesirably affecting the RFID device. The inlaymay also be affixed directly to the product without necessarily beingincorporated into a label or tag, such as through use of an adhesive toaffix the inlay to the product.

In some exemplary embodiments, the products can be arranged into sheetsor rolls, and multiple products can be printed, encoded, or verified atone time, in a sequential manner, simultaneously or substantiallysimultaneously. In some exemplary embodiments, reader and chip/antennaconfigurations can allow the encoding and verification to occur in line,so that printing, encoding, variable data imaging, verifying, andfinishing can all be completed in one continuous process. As used hereina continuous process includes both a roll to roll configuration, and asheet fed process in which there is no stopping of the process.Continuous may also include a slight incremental stopping, indexing,advancing or the like which does not last longer than a couple ofseconds.

Furthermore, a cutter (not shown) can also be included in the printer100. The cutter would be used to cut the web being printed on and theRFID tags disposed thereon. Typically, the cutter would be powered fromthe printer 100, or can be powered by any suitable means as is known inthe art.

Printing as provided herein may be accomplished by using any number ofprocesses, including impact and non-impact printers, flexographic,gravure, ink jet, electrostatic and the like just to provide somerepresentative examples. Static printing may include company logos,manufacturers' information, size, color and other product attributes.Variable printing may include unique information read from the RFIDtransponder, identification numbers, bar codes, pricings, store locationand such other information as a retailer may decide is required.

Exemplary RFID devices, e.g. inlays, tags, labels and the like areavailable from Avery Dennison RFID Company and Avery Dennison RetailInformation Services of Clinton, S.C. and Framingham, Mass.,respectively. Such devices may be provided in any number of antenna andsize configurations depending on the needs or end-use applications forwhich the product is intended.

FIGS. 1-7 disclose multiple views of the industrial printer 100, and aredescribed below. The printer 100 can be any suitable size, shape, andconfiguration as is known in the art without affecting the overallconcept of the invention. One of ordinary skill in the art willappreciate that the interior and/or exterior shape of the printer 100 asshown in FIGS. 1-7 is for illustrative purposes only and many othershapes of the printer 100 are well within the, scope of the presentdisclosure. Although dimensions of the printer 100 (i.e., length, width,and height) are important design parameters for good performance, theprinter 100 may be any shape that ensures optimal high speed encodingand verification.

Generally referring to FIG. 1, the thermal tabletop and industrialprinter 100 has a generally rectangular shape with a printer cover 101.However, tabletop printer covers can be cumbersome to remove whenstandard screws are used to fasten the cover down. Thus, in a preferredembodiment, the standard screws are replaced with thumb screws 103 (asshown in FIG. 11). The thumbscrews 103 can be any suitable thumbscrew103 as is known in the art, and allow a user to easily remove theprinter cover 101 whenever necessary without need of a screwdriver orother such tool.

Further, the printer 100 comprises an access hinged cover 32 and handle1. The hinged cover 32 can be actuated via the handle 1 to provideaccess to the front of the printer 100 and to load supplies. Once thehinged cover 32 is opened, the user installs the supply roll 3 on thesupply roll holder 4. The supply roll 3 contains supplies for theprinter 100 to print on. Then, a liner take-up table 5 acts as a rewindholder for spent liner for adhesive backed labels. The printer 100further comprises a front door 12 to provide additional access to theinterior of the printer 100.

Furthermore, the printer 100 comprises a supply damper 6 that helps toremove vibration from the supply roll 3 to improve print quality. And,an out of stock switch 7 provides an on/off indication if supplies areloaded in the printer 100, or if the printer 100 is in need of supplies.A supply guide or frame 8 holds and centers supplies. Further, an arraysensor (shown in FIG. 2 as 35) is attached to the supply guide 8 todetect and accommodate minor variations in aperture location. An upperguide 11 guides supplies within the printer 100, and a loading label 18(FIG. 2) is a label indicating the supply path for users to loadsupplies into the printer 100. In one embodiment, the upper guide 11includes a lighted paper path to illuminate the supplies for the user.The printer further comprises a print head 14. The print head 14 is athermal print head such that the printer 100 automatically detects dotdensity and the location of failed heating elements. Additionally, theprinter comprises a print head holder 15 which is a cast aluminum piecethat the print head 14 is installed on to secure the print head 14 inplace. Further, a printhead release tabs 36 (FIG. 2) releases the printhead 14 from the holder 15 when needed. In order to get access to thesupply path printhead latch 10 will unlatch the printhead from supplyguides 8. Further access can be gained by opening Front Door 12revealing exit path.

The printer 100 also comprises a ribbon spindle 16 and a ribbon take-up17. The ribbon spindle 16 is a DC motor-controlled supply for ribbon,and the ribbon take-up 17 is a DC motor-controlled takeup for ribbon.Further, a wireless antenna 2 is also included within the printer 100.The wireless antenna 2 is an 802.11 b/g/n dual band antenna forcommunicating with a router or other device. Additionally, the printercomprises two other antennas connected to intentional transmitters andtwo passive RFID antennas. An RFID antenna 9 to allow for the RFIDencoding of supplies, and an RFID verifier 13, which is an externalantenna for reading RFID supplies. It is noted that the power used forthe second RFID module controlling the verify antenna can be either theread power from the first RFID module or the write power from the RFIDencode module. I²C NFC 1356 MHz antenna is attached to the mainprocessor contained on 29 (as shown in FIG. 7). Underneath the supplyguides 8 is a UHF Temperature Sensor 37 (as shown in FIG. 7) whereasRFID Encoder Antenna 34 can be used to read the operating temperature ofthe printer for the purpose of improving print quality.

Generally referring to FIG. 2, the printer 100 comprises an overhead LED(light emitting diode) sensor cap (not shown) which covers an overheadLED board 20 which is a reflective supply sensor LED. Further, theprinter includes an LED cap 21 which is a reflective supply sensorreflector, and an index sensor 35 which is a unique array sensor thatautomatically detects aperture sense marks. The index sensor 35comprises a sensor cap 19. Print head release tabs indicated byreference numeral 36 are illustrated in FIG. 2 to aid in easy release ofthe print head 14. Specifically, the lighted sensor array 35automatically senses the position of holes disposed through the webwhich are used for sense marking, and correctly indexes the printing tothe RFID tags. By using the sensor array 35, the printer 100 candetermine which of the individual sensors within the array should beused for the indexing to account for manufacturing variations in theplacement of the aperture.

Generally referring to FIG. 3, the back of the printer 100 comprises aback cover 26 that covers the electronics panel (shown in FIG. 4). Adisplay panel 25 displays a user interface, and the wireless antenna 2(as shown in FIG. 1) can also be seen on the back of the printer 100.Generally referring to FIG. 4, the back of the printer 100 is shownwithout the cover 26. A CPU board 29 or main PC board is shown, as wellas the RFID I/O board 27 which is a module that contains both theencoding and verification modules. A power supply 28 which is the mainsupply for power in the printer 100 is also shown at the back of theprinter 100. Furthermore, the display panel 25 (as shown in FIG. 3), andthe wireless antenna 2 (as shown in FIG. 1) can both be seen in FIG. 4as well.

Generally referring to FIG. 5, the right side of the printer 100 isshown. The right side of the printer 100 shows the access door 32, aswell as the wireless antenna 2 (as shown in FIG. 1). Further, the CPUboard 29 (as shown in FIG. 4) is shown, as well as an I/O switch 30 andan I/O outlet 31. Generally referring to FIG. 6, the left side of theprinter 100 is shown. The left side of the printer 100 shows thewireless antenna 2 (as shown in FIG. 1), as well as a supply door 22that secures and allows access to the supply roll 3. Further, a NFC I2Cchip 23 is also disclosed which provides unique capability to theprinter 100 and allows the printer 100 to communicate directly with themain processor through a bridge. The present invention contemplates thatcommunication to the printer's main processor can use Near FieldCommunication (HF RFID) for both forward and reverse data. Finally,display panel 25 includes a keypad 24.

In a preferred embodiment, the printer 100 includes a plurality of keysincluding the keypad 24 and a trigger key (not shown). The keypad 24 maybe utilized to enter alpha-numeric data to the printer 100.Alternatively, the keypad 24 may have only a limited number of keys thatare actuable in accordance with information depicted on the display 25for selecting a number of operations of the printer, for example,feeding a web of record members through the printer 100, displayingstatus information, etc. The trigger key may be actuable by a user invarious modes of the printer 100 to actuate the printing system and/or aRFID read/write module 34. Alternatively, one or more of these devicescan be actuated automatically by a controller of the printer 100 inaccordance with a stored application program. In addition to displayingstatus information or data entered via the keypad 24, the display 25 mayalso be controlled to provide prompts to the user to actuate the triggerkey and/or other keys so as to control various operations of the printer100.

Generally referring to FIG. 7, the top, perspective view of the printer100 discloses the RFID verifier 33 and the RFID encoder 34 (as shown inFIG. 1 as antennas 9 and 13 respectively), as well as UHF TemperatureRFID Tag 37. Specifically, the RFID encoder 34 encodes RFID tags whilethe web is moving, and the RFID verifier 33 verifies the data encoded tothe RFID tags. Furthermore 23 indicates the location of the I2C NFCantenna connected to main processor. Antenna 37 is a passive UHFtemperature sensor which allows RFID Encoder 34 to gain access to theoperating temperature of printer 100 for the purposes of optimizing theprint conditions.

Specifically, the industrial printer 100 comprises two RFIDreader/writers (33 and 34) that are individually controlled, allowingthe industrial printer 100 to encode and verify at the same time. Thus,the industrial printer 100 comprises both an RFID writer or encoder 34module and an RFID verifier 33 module that operate independentlyencoding and verifying RFID transponders within the label, tag, or otherconstruction media. The two RFID modules cooperate with each other andwith the processor of the industrial printer 100. The RFID encodermodule 34 encodes the desired information to the RFID transponder whenthe transponder reaches the encoding location. The RFID verifier module33 reads the transponders and compares it with information provided bythe printer controller. Then, any stock that contains a failed RFID mayoptionally be marked by the print mechanism, so as to designate it asdefective with a visual indication for the user, and the failedverification will be sent to a host for data logging purposes.

Furthermore, typically RFID output power is set to what is necessary toencode the transponder that is electrically singulated in the RF field.When electronically singulated there is no other singulation for thetransponders therefore it is expected that there is only one transponderpresent in the RF field at a time. However, the transponder positionedover the antenna may be defective or less sensitive to the set powerlevel such that an adjacent transponder is acquired by the antenna andtherefore encoded. Thus, to prevent misreads or other errors such asduplicate tags with the same encoded data, the printer 100 may useadaptive RFID power settings.

Specifically, two power levels are employed to assist in the electricalsingulation by software singulation. As reading the contents of atransponder requires less power than encoding it, a sufficiently lowpower level is used to create an RF field small enough in strength sothat the only transponder acted upon is the one positioned immediatelyover the antenna. At this read power level, the serialized tagidentification (TID) field of the RFID transponder would be read andsaved. Next, the power level would be increased to the level necessaryto write the tag. The TID serial number would be included in the encodecommand to singulate on the particular tag containing the serial numberand ignore any adjacent tags that may accidently be in the RF field.Finally, the RF power level is reduced back down to the selected readlevel, such that the RFID verifier can read and compare the encoded dataof the tag with the data originally sent in the write command to confirmthe tag is accurately encoded. If the inlay over the encoding antennacan be determined from other transponder characteristics such as theRSSI it would be unnecessary to employ two power levels.

Furthermore, it is known that there is variation within a supply rollfrom RFID transponder to RFID transponder. The disclosed printer 100 mayutilize an adaptive algorithm that will allow for a variation intransponders without generation of an error. This algorithm will startat a read power low enough not to detect a transponder and then willincrement up in steps until a transponder is seen. For the nexttransponder, the previous detection point will be used as a startingpoint and then will increment up if needed. If more than one transponderis detected the read power will be reduced. If no transponders aredetected, then the read power will be increased until a transponder isdetected. The selected power will then be used as a starting point forthe next transponder and so forth.

Generally referring to FIGS. 8A-B, the microprocessor controls theprinter 100 of the embodiments of the present invention to encode, writeto and/or read an RFID transponder in a label and to print on that samelabel. At block 800, the processor controls the printer motor to feed alabel into position at which point the movement of the label web isstopped. Once the label is in position, the RFID transponder will begenerally aligned with the antenna. At block 802, the microprocessorretrieves data from the memory that has been sent from the host forwriting to the RFID transponder. This data may be for example electronicproduct code (EPC) information or other data. Thereafter, at block 804,the microprocessor generates a program command. The program command is apacket of control information to be sent to the RFID interrogator ormodule. From block 804, the microprocessor proceeds to block 806 to sendthe generated packet to the RFID module i.e. interrogator.

It is noted that in a preferred embodiment, the RFID module orinterrogator includes its own microprocessor. The RFID module performs anumber of functions. For example, the module determines whether an RFIDtransponder is within its field by reading the RFID transponder'sidentification code. The RFID module as instructed by the controller mayerase the data stored in the RFID transponder, may verify the erasureand then programs the RFID data received from the microprocessor intothe RFID transponder. The RFID module also verifies that the data hasbeen programmed into the RFID transponder by reading the data stored inthe transponder after a programming operation to verify that the datawas correctly written into the RFID transponder. Upon completing theverification process, the RFID module generates a response packet thatis transmitted back to the microprocessor.

The microprocessor, at block 808, receives the response packet from theRFID module and at block 810, the microprocessor extracts data from theresponse packet. The data in the response packet may include a coderepresenting the successful programming of the RFID transponder or thedata may include a code representing a particular error. For example,the response data may include an error code indicating that the RFIDmodule could not read an RFID tag, or a code indicating that the tagcould not be erased or a code indicating that the tag was not accuratelyprogrammed. At block 812, the microprocessor decodes the data in theresponse packet to determine at block 814 whether the programming of theRFID transponder was successful or whether the response packet from theRFID module included an error code. If the programming of the RFIDtransponder was determined to be successful, that is, without error, atblock 814, the microprocessor proceeds to block 816 to control thefeeding or movement of the web and the printing of data on the label viathe print head. It is noted, that while the RFID transponder is beingread from or programmed, the web may be stationary. However, during theprinting of information on a record member at block 816, themicroprocessor moves the web past the print head during the printingoperation. If the microprocessor determines at block 814 that theresponse packet received from the RFID module indicated an errorcondition, the microprocessor proceeds to block 818 to display an errormessage on a liquid crystal display of the printer. From block 818, themicroprocessor proceeds to block 820 to feed the label with thedefective RFID transponder past the print head and controls the printhead to print an overstrike image, such as evenly spaced longitudinallyextending bars, on the record member RM. This indicates that the RFIDtransponder is defective. From blocks 816 or 820, the microprocessorproceeds to block 800 to feed the next label into position as discussedabove.

Furthermore, in a preferred embodiment, the thermal printer 100 alsoprovides for optimized RFID encoding by reducing the time required tocomplete a user defined function. A user sequence may include thefollowing command sequence that will select a tag, write the 8 banks ofthe EPC memory, write the access password in the reserved memory and setthe lock memory to password lock and then read the 8 banks of the EPCmemory. In a RFID printer with a RIFD writer (interrogator) there aretwo opportunities for optimization. The RFID printer communicates acrossa communication channel for example serial, USB or other method to aRFID writer that contains an independent processor. This communicationinvolves a handshake and necessary error processing. If it is alreadyknown that a sequence of commands will be sent to the RFID writer, theimplementation of a command stack sent in one sequence will eliminateunnecessary overhead between the RFID printer and the RFID writer.

Generally referring to FIG. 9A, traditional communication operation 900would involve the RFID printer 901 issuing individual commands for WriteEPC 902, Write Access 904, Password Lock 906, and Read EPC 908, then theRFID interrogator 903 would process each command (902, 904, 906, and908) and respond 910 after each command creating unnecessary overheadbetween the RFID printer 901 and the RFID interrogator 903. Generallyreferring to FIG. 9B, the RFID printer 901 creates a high level commandoptimization operation 907, wherein the RFID printer 901 issues theindividual commands of Write EPC, Write Access, Password Lock, and ReadEPC as one command 912, allowing the RFID interrogator 903 to processall the commands 912 at once and then respond 914, saving time andeliminating the unnecessary overhead between the RFID printer 901 andthe RFID interrogator 903.

In addition, between the RFID writer and the RFID tag there is ahandshake that can be optimized if there is pre-knowledge that a set ofhigh level commands will be sent. The handshake process can be optimizedif there is no reason to power down the RFID tag. However, one reasonthe RFID tag may need to be powered down is to change the power level toa different power. For instance, if the RFID tag EPC memory was writtenat one power and the RFID tag EPC memory was read at a different power,then a power down is necessary.

Furthermore, EPC RFID access commands must follow an inventory to obtainthe tag handle REQ_RN. For each access (Read, Write, Kill, Lock) commandthat is done this sequence must be followed. For a thermal barcodeprinter with an RFID writer this sequence contains redundant steps ifmore than one access command is executed after the tag has been acquiredsince the REQ_RN handle must be reacquired for the same tag for eachaccess command. The EPC Gen 2 (or EPC Cl Gen 2—electronic product codeclass 1, generation 2) protocol specifies that as long as the tag ispowered on it must retain the REQ_RN handle. Thus, in order to optimizethe command sequence, the select and inventory commands issued for eachaccess command have been optimized out as long as the tag is powered on.

Generally referring to FIG. 10A, the traditional communication processof a high level command sequence, for illustrative purposes thefollowing commands: Write EPC, Write Access Code, Lock Tag, ReadEPC;without foreknowledge of communication requires the RFID Interrogator1053 for to issue the command sequence for encoding the 96 bit EPC, aquery command 1058 and the RFID tag 1059 will respond RN_16 ,1060, thenthe RFID Interrogator 1053 issues Ack (RN16) 1058 and the RFID tag 1059responds with PC, EPC & CRC-16 1060 to identify the command stream. Thenthe RFID Interrogator 1053 issues REQ_RN 1058 and the RFID tag 1059issues the handle (New RN16) 1060, then the RFID Interrogator 1053issues the Write Command 1058 and the RFID tag 1059 responds with theStatus—Success, Error Failure 1060. At this point the RFID Interrogator1053 issues Read PC bits and ReqRN 1058 to which tag 1059 responds withthe EPC. Since the RFID Interrogator had not preprocessed the commandsequence in Encode Access Password the chip must be powered on andtransitioned to the Open state. 1062. RFID Interrogator 1053 reissuesthe Query, ACK, ReqRN, ReqRN before writing the Access Password in 1062.The tag 1059 will respond appropriately in 1064 to these commands. Nextthe RFID Interrogator 1053 will issue the command sequence required tolock the tag 1059. Since the tag 1059 was not kept in the open state theRFID Interrogator 1053 will need to reissue Query, ACK, ReqRN, ReqRN1066 before locking tag 1059. Tag 1059 will respond appropriately 1068.A final read is shown in 1074 that could be used for validation purposesto ensure accuracy. The tag 1059 is starting from power on the Query,ACK and Query Rep need to be issued from RFID Interrogator 1053 to whichtag 1059 responds in 1072. However, if the RFID Interrogator 1053already has knowledge of a command stream as illustrated in FIG. 10B,then the select and query commands become redundant, and theinterrogator 1053 and the chip (or tag 1059) only need to issue theReq-RN 1020 before receiving the next access command 1022. Thus, asillustrated in FIG. 10B, the communication process with foreknowledge ofthe communication sequence discloses the RFID Interrogator 1003 issuingthe next access commands 1016 and 1022 to encode the Access Password theQuery and ACK are eliminated to increase the encoding throughput. Req_RNcommand at1022 followed by the 32-bit write to the access password. RFIDtag 1009 at 1024 issuing the handle (New RN 16) 1024 and the RFIDInterrogator 1003 responding with the Access Command 1026 and the RFIDtag 1009 responding with the Status—Success, Error Failure 1028. Thisprocess is continued to be followed in 1026 for the lock command. In1028 the tag 1009 responds appropriately. If it is desired to do a finalread to ensure encoding accuracy if the read is at the same power theprocess between 1053 and 1009 is shown streamlined in 1030 and 1032.Thus, with knowledge of a command stream, the communication sequencebetween the interrogator 1003 and the chip (or tag 1009) can beoptimized via removal of the query and Ack commands between the accesscommands. This optimization reduces the overall cycle time.

Further, a composite RFID Interrogator Host Write memory command whichprovides for successive writes to various memory blocks in a RFID Gen 2Tag device before returning the results of the command to the host canbe utilized to optimize system throughput. This command accepts memoryblock identification for each memory block to be written and data to bewritten into each memory block. The RFID Interrogator executes thenecessary Gen 2 RFID tag device commands to place the tag into the OpenState and then proceeds to execute to Gen 2 the successive Writecommands to the various memory blocks, defined in the host command.

Further a composite RFID Interrogator Host Write memory command whichprovides for successive writes to various memory blocks in a RFID Gen 2Tag device before returning the results of the command to the host canbe utilized to optimize system throughput. This command accepts memoryblock identification for each memory block to be written and data to bewritten into each memory block. The RFID Interrogator executes thenecessary RFID Gen 2 tag device commands to place the tag into the OpenState and then proceeds to execute to Gen 2 the successive Writecommands to the various memory blocks defined in the host command.

When all memory blocks have been written, the RFID Interrogator returnsthe tag device to the ready state and returns the status of the resultsto the host.

Furthermore, optimization of the thermal printer occurs with successivewrite and verify commands. Specifically, a composite RFID interrogatorhost write/verify command which provides for multiple writes to variousmemory areas in an RFID Gen 2 tag device where the tag device is left inthe Open state for the duration of the entire set of commandwrite/verification operations is utilized. The command is executed intwo stages. In the first stage, the command is defined as a record witha unique ID, followed by a flag that specifies whether an optional tagidentification (TID) is to be used for identifying the tag to be writtento. This is followed by one or more write directives, where eachdirective is comprised of the memory bank to write to, the word offsetinto the memory bank to begin writing, the number of words to write, anda flag that indicates whether the write is to be verified.

In the second stage, the data to be encoded for each tag is sent as arecord beginning with a unique ID that matches the ID defined in thefirst stage, followed by an optional TID used to identify the tag in theRF field, followed by one or more write directives that match the writedirectives defined in stage 1. In this record each write directivecontains the actual data to be written to the memory areas specified instage 1. After writing, the specified memory banks optional verificationread could occur in the same state If the chip architectures requires anew session for the verification read, this will be done immediatelyafter the write phase. Upon completion of the write and verificationphases the Interrogator returns the tag device to the Ready state andreturns the results of the command to the host.

Thus, this composite RFID Interrogator Command Stack which optionallymay contain Host Write memory command would be used in the RFID enabledthermal barcode printer 100 which would allow a user to print and encodean RFID label without stopping the web to encode the RFID tag device.Further, the overall RFID tag device encode time is reduced, whichallows for the supplies web to move through the printer continuously,without stopping to encode the device. As a result, more RFID tags perminute can be produced thus increasing printer productivity. This higherproductivity would increase printing capacity to meet demand.

Generally referring to FIGS. 1-7, an exemplary embodiment of a systemwhich may include at least a printer 100 and encoder/verifier is shown.Printer 100 can print through flexographic, offset, gravure, digitaloffset or xerographic digital processes, or any other desired printprocess. Printer 100 can accept input information in any format, forexample Java Script Object Notation, Portable Document Format (PDF),Personalized Print Markup Language (PPML), or any other desired format.The information is typically provided from a computer which may eitherbe collocated with the printer 100 or may be provided in a remotelocation. The printer 100 may be connected to the computer via anintranet or over the Internet, depending on the requirements of themanufacturing operation. Printer 100 can also include one or more RFIDreaders and RFID encoders 34 (as shown in FIGS. 1-7, such as for exampleFIG. 7) which can be arranged in any configuration, for example in aconfiguration that allows RFID encoding to occur in line, either beforeor after printing.

In exemplary embodiments, printer 100 can contain multiple RFID readersand RFID encoders 34, arranged in such a way that allows multipleproducts, for example in sheet or roll form, to be printed and encodedas part of a continuous process. It should be understood that the readerand encoder can be combined in a single unit or provided in a twoseparate components. Printer 100 can also comprise an RFID verifier 33that verifies the data encoded by the RFID encoder 34. The RFID encoder34 and RFID verifier 33 are individually controlled such that encodingand verifying can occur at the same time. Printer 100 can also isolateadjacent products from radio-frequency cross-coupling and interferenceusing physical screening, for example with a moving shutter, electricalscreening, for example using infrared light or an interfering carriersignal, or by any other desired method for providing electricalshielding.

Still referring to FIGS. 1-7, printer 100 can also have a qualitycontrol system (not shown), such as a vision inspection system, RFIDtest system or other device to ensure adequate quality in the unit.Quality control system can be located in line with the printer 100, orit can be located off line, such as with a remote RFID test station.Quality control system can include one or more RFID readers and RFIDencoders 34, which can allow quality control system to check productsfor errors in RFID encoding. Quality control system can also includeoptical readers or scanners in any desired configuration, which canallow quality control system to check products for errors in printing.Quality control system can further include a die cutter, which can allowthe system to separate improper or defective products so that they canbe discarded or reprocessed. RFID products that are detected as beingdefective can be marked or otherwise identified so that they can beremoved from the web or sheet during manufacturing or inspection or canbe easily recognized by the customer so that the end user does not usethe defective tag as part of RFID tag or label.

Referring generally to the figures, printer/encoder 100 can encode RFIDdevices using full encoding or it can encode RFID devices or productsusing partial encoding with the remainder of the coding to be completedby the end user such as a retail or brand owner. When using fullencoding, printer/encoder 100 may fully program each RFID device orproduct individually. This programming can occur all at once (e.g.substantially simultaneously) or in stages, in an incremental fashion oras desired. When using partial encoding, printer/encoder 100 can programeach RFID device or product with only a portion of the information thatis to be stored on the products. This programming can occur all at onceor in stages, as desired. For example, when using EPCs and partialencoding, printer/encoder 100 can receive a sheet of RFID products thathave already been programmed with the portion of the EPCs that arecommon to all RFID products in the sheet, batch of sheets or roll. Thiscan allow printer/encoder 100 to save time by only encoding each RFIDdevice or product with variable information that is different for eachproduct in the sheet or roll. In some embodiments, fixed data fields canbe encoded and the unique chip identification number can be used as theserialization.

In another embodiment, the printer 100 includes a microprocessor and amemory (not shown). The memory includes non-volatile memory such asflash memory and/or a ROM such as the EEPROM. The memory also includes aRAM for storing and manipulating data. In accordance with a preferredembodiment of the present invention, the microprocessor controls theoperations of the printer 100 in accordance with an application programthat is stored in the flash memory. The microprocessor may operatedirectly in accordance with the application program. Alternatively, themicroprocessor can operate indirectly in accordance with the applicationprogram as interpreted by an interpreter program stored in the memory oranother area of the flash memory.

The microprocessor is operable to select an input device to receive datatherefrom and to manipulate the receive data and/or combine it with datareceived from a different input source in accordance with a storedapplication program. The microprocessor couples the selected, combinedand/or manipulated data to the printing system for printing on a recordmember. The microprocessor may select the same or different data to bewritten to an external RFID chip. The microprocessor couples the dataselected for writing to the RFID read/write module wherein the data iswritten in encoded form to the external RFID chip. Similarly, themicroprocessor can select the same or different data for storage in atransaction record in the RAM and for uploading via the communicationinterface to a host. The processor is operable to select data to becoupled to the printing system independently of the data that theprocessor selects to be coupled to the RFID read/write module to providegreater flexibility than has heretofore been possible.

Generally referring to FIG. 12A, the industrial printer 100 comprisestwo RFID reader/writers (33 and 34) that are individually controlled,allowing the industrial printer 100 to encode and verify at the sametime. Thus, the industrial printer 100 comprises both an RFID writer orencoder 34 module and an RFID verifier 33 module that operateindependently encoding and verifying RFID transponders within the label,tag, or other construction media. The two RFID modules cooperate witheach other and with the processor of the industrial printer 100. At 200,a label is fed into position, and then at 202 the RFID encoder module 34encodes the desired information to the RFID transponder when thetransponder reaches the encoding location. At 204, the RFID verifiermodule 33 reads the transponders and at 206 compares it with informationprovided by the printer controller. Thus, the two RFID reader/writers(33 and 34) are operated independently (see 208), allowing theindustrial printer 100 to simultaneously encode and verify the RFIDtransponders within the RFID labels (see 210). At 212, it is determinedwhether the RFID tag contains a failed RFID. Then, at 214 any stock thatcontains a failed RFID may optionally be marked by the print mechanism,so as to designate it as defective with a visual indication for theuser, and the failed verification will be sent to a host for datalogging purposes (see 216). It may be advantageous to place a shieldbetween the two RFID reader/writers 33 and 34 as shown in 1820 FIG. 18to minimize the cross talk between the two RFID reader/writers 33 and34.

Specifically, two power levels are employed to assist in the electricalsingulation by software. As reading the contents of a transponderrequires less power than encoding it, a sufficiently low power level isused to create an RF field small enough in strength so that the onlytransponder acted upon is the one positioned immediately over theantenna. At this write adjust power level, the serialized tagidentification (TID) field of the RFID transponder would be read andsaved. Next, the power level would be increased to the level necessaryto write the tag. The TID serial number would be included in the encodecommand to singulate on the particular tag containing the serial numberand ignore any adjacent tags that may accidently be in the RF field.Finally, the RF power level is reduced back down to the selected writeadjust level, such that the RFID verifier can read and compare theencoded data of the tag with the data originally sent in the writecommand to confirm the tag is accurately encoded.

Furthermore, it is known that there is variation within a supply rollfrom RFID transponder to RFID transponder. The disclosed printer 100utilizes an adaptive algorithm that will allow for a variation intransponders without generation of an error. This algorithm will startat a writer adjust power low enough not to detect a transponder and thenat 316 will increment up in steps until a transponder is seen. For thenext transponder, the previous detection point will be used as astarting point and then will increment up if needed (see 318). If morethan one transponder is detected the writer adjust power will bereduced. If no transponders are detected, then the writer adjust powerwill be increased until a transponder is detected. The selected powerwill then be used as a starting point for the next transponder and soforth. If this is not sufficient to uniquely identify the transponderthe singulation process will be enhanced as follows.

Generally referring to FIG. 12B, two power levels are employed to assistin the electrical singulation by software. As reading the contents of atransponder requires less power than encoding it, a sufficiently lowpower level is used in step 300 to create an RF field small enough instrength so that the only transponder acted upon is the one positionedimmediately over the antenna (see FIG. 21, 22000). At this writer adjustpower level, the serialized tag identification (TID) field of the RFIDtransponder would be read and saved (see 302). At 304, the power levelis increased to the level necessary to write the tag. At 306, the TIDserial number would be included in the encode command (see 312) tosingulate on the particular tag containing the serial number and ignoreany adjacent tags that may accidently be in the RF field. At 308, the RFpower level is reduced back down to the selected read level, and at 310the RFID verifier can read and compare the encoded data of the tag withthe data originally sent in the write command to confirm the tag isaccurately encoded.

In FIG. 13, 1310, shows a representation of a web of tag supply withaperture holes. Reference numeral 1540 (see FIG. 15) indicates oneembodiment of the aperture on the tag located on roll 1310 that bepushed past sensor 1410 (See FIG. 14) retained in supply guide 8. In oneembodiment the aperture hole enables light to pass from the emitter tothe detector as it moves by the sensor array indicated by 1810 on FIG. 8which obtains the reference voltage by using the controller logicretained on CPU board 29. The aperture or break in the supply 1310 willnormally exceed the focal point of one of the sensors contained in 1410.The aperture or break in supply 1510 can be aligned anywhere alongsensor 1410.

Prior to running supplies 1310 through printer 100 it would be expectedthat the calibration processes initiated in process 1610 depicted onFIG. 16 would be completed. The flow of calibration is to prompt theuser if they would like to calibrate aperture supply, 1620, if not theprocess exits in 1630. If the user wishes to continue he is prompted toalign the aperture in sensor 1410 installed in printer 100 for thecalibration process. The diameter of the aperture shown by referencenumeral 1540 in FIG. 15 must be placed in sensor 1410 prior to moving todecision point 1660. The user is prompted verify that the supplies areproperly aligned in 1660 prior to moving the 1670 to acquire the actualvoltage. The read voltage is compared to the desired reference voltageif the read voltage in 1670 meets or exceeds the reference voltage theprocess is completes and exits in 1680. If the read voltage is less thanthe reference voltage the power is increased to the sensor in 1640 andthe read voltage is acquired again.

When printer 100 prepares to move web 1310 showing a feed direction in1530 the selected media sensor enters the process of checking whichsensor is being used, 1710 on FIG. 17. Prior to testing the sensorsthere is a test to determine if the web is moving in 1750. If there isno movement the process exits in 1730. If the aperture sensor isselected 1720 the process continues to 1740 or else the process exits in1730. In 1740 the voltage determined in 1670 is applied to sensor 1410.The voltage is acquired from sensor 1410 in 1760. A test is completed in1770 to determine if the reference voltage matches or exceeds thereference voltage. If not the process returns to 1720 if the referencevoltage does exceed reference voltage in 1780 it is recorded that a markis seen and the process terminates in 1790. This process represents oneexample of control logic for sensor 1410. In other examples is presumedthat hysteresis would be added to the control logic depicted in FIG. 17to prevent false readings of a mark.

In FIG. 19, 1910 shows checking the status of the printer 100 in orderto set a backlight for the display shown in 25 on printer 100. When thestatus of the printer 100 is determined one of four paths are followed:1920 is if the status of the printer is idle the backlight will be setto white; 1930 if the status of the printer is offline the backlight isset to white; 1940 if the status of the printer is active the backlightis set to green; 1950 if the status of the printer is an operatorintervention required the backlight is set to red. Finally, the processenters the subprocess 1960 to count down the system flag status check.If 1970 when the count reaches zero, we reenter 1905 to reset theinterval counter and then check the current status of the industrialprinter in 1910.

An RSSI singulation process begins with 2010 in FIG. 20A. Printer 100either backfeeds or forward feeds in order to center the metal of thefirst candidate inlay over the centerline of the coupler depending onthe value of tag save as indicated by 2020. The amount of distance tooverfeed, 2040, or backfeed, 2030, as determined by the user inidentifying the ideal couple point which will be referred to as firsttid position.

In step 2050 the power is set to a write adjust power and (in 2060)attempt to read a 96-bit TID. In 2070 it is determined if a 96 bit tagis successfully read. If yes, the method continues on to 2100, where theweb can be encoded while moving; if the web is not encoded while moving,in step 2090 the process stops encoding. If the web is encoded whilemoving the inventory command tag population is taken at step 2140. If wefail to read a 96 bit transponder at 2070, the process continues to step2080. On step 22080 the system attempts to read a 64 bit transponder in2120. If we fail, we will record the error as 739 and go to 2130. Ifsuccessful, we go to step 2100. In 2100 we determine if we are encodingwhile the web is moving. If this is a stop to encode case we go to 2190.

In the case of encoding while the web is moving we will do a taginventory with the tag population set to 4. If from the tag inventory wereceive 0 tags, we will record error 741 and go to error processing2130. If we find 4 or more transponders, we will record error 727 and goto error processing 2130. If there is only one transponder, we willdetermine if we are going to move forward or reverse in step 2190. Ifthere are 2 or 3 tags the RSSI values will be compared in step 2160. Ifthere is not a transponder with a count return signal strength indicatorof 100 or more at 2170, we will record error 740 and proceed to errorprocessing 2130. If there is a candidate transponder indicated by theRSSI we will processed to step 2190 to determine motion direction.

In step 2190 depending on the user selection of the Tag Saver value wedetermine the motion. If the value is yes, we processed to the tag saverfunction in 2210 if the value is no we processed to encoding thetransponder in 2200.

For encoding the transponder in 2200 we will proceed to 2270 todetermine the number of transponders located as illustrated in FIG. 20B.If there was one transponder located, we encode it in 2260 and proceedto the finish encode in 2250. If the number of transponders in 2270 isgreater than 1 we go to 2280 to advance the encode zone into the RFIDencode antenna. If 2290 we perform another inventory with a transponderpopulation set to 2. In 2300 we determine the number of transpondersthat responded. If the number is less than 1 or greater than 2 we recordthe error as 740 and proceed to error process 2130. If there was one tagresponding in 2320 we determine if we have already seen thistransponder. If we have, we record the error as 740 and proceed to errorprocess 2130. Is this the first time we have seen this transponder weproceed to encoding in 2340. Backing up to step 2300 if two tagsresponded we processed to 2310 where we decide if one of the tags hasbeen seen before. If not we record the error as 740 and proceed to errorprocess 2130. If we have seen on of the transponders before we proceedto select new transponder in 2330 and proceed to 2340 to encodetransponder.

In 2340 we encode the transponder with the new data setting S3 andproceed to finish encoding in 2250.

If after 2190 it was determined that the tag saver was desired by theuser in 2210 we proceed to 2220 to reverse motion the transponder overthe RFID encoding antenna show in FIG. 21 22000. The tag inventory withthe transponder population set to 1 in 2240 is performed. If only 1transponder responds we proceed to 2340 to encode the required data intothe transponder. If there is any other response error 736 is recordedand we proceed to error processing 2130.

After 2130, the method proceeds to finish encode in 2250. A decisionpoint is reached if we have more inlays to process as required by theuser in 2350 as illustrated in FIG. 20C. If there is no decision point,then in step 2400 a done state is reached. If there are more inlays toprocess, we increment the step count 2360 for the RFID process and thenlook to see if the step count is equal to the next inlay position in2370. If no, return to increment the step count. If yes, we do aninventory with a transponder population set to 1 setting S2 in step2380. If there, do a check in 2390 if we located 1 transponder. If wedid, in 2410 we encode the transponder with the required data andproceed to 2350 decision. If there is any other response, we set theerror code to 741 or 736 and proceed to error processing 2130.

If at decision 2100 we took the stop to encode path this is the processas illustrated in FIG. 20D. In 2090 we proceed to determining if themotion is stopped in 2420. If no, we return wait. If yes, we proceed to2430 and do a tag inventory with the population set to 4. If we received0 or more than 4 tags responding in 2440 we mark the error code andproceed to error process 2130. If there was 1 tag, we proceed to 2470.If we received 2 or 3 tags, we compare the RSSI value at 2450. In 2460we check to see if we have an RSSI value of on tag that is at 100 countsgreater than the other tags. If no, we mark the error code 740 andproceed to error process 2130. If yes, we proceed to 2470 and encodewith the required data.

In 2480 we determine if there are more transponders to encode; if yes wereturn to decision point 2420. If no, we proceed to a done state at2400.

The error process as illustrated in FIG. 20E is brief;—at 2130 we enterthe error process. On 2490 we stop motion of printer 100 and inform theuser there is an error then proceed to the done state 2400.
